... was built using maps generated from an integrated study of seismic and 65 key wells. The depth to basement and depth to Moho were incorporated from previous gravity modelling study. The CO 2 content and isotope data compiled from reports facilitated in building the knowledge on the source, origin...

... of top basement of OVT gather. Figure 3 The stack results of different azimuth section and ellipse fitting, it shows that the more azimuths divided, the worse the stack seismic data quality; if the ellipse fitting is low, it will increase the calculation time. Finally, the solution in picture...

... Abstract Owing to the depleting reserves in the conventional reservoirs over the last few years, unconventional reservoirs have gained significant importance in the exploration of oil and gas. Basement rocks, though non-sedimentary in origin, is looked upto as one of the important...

... seismic, the study provided an insight into the structural architecture of the near surface and occurrence of shallow gas. The seismic data was of such high quality that attributes such as Variance and Dip Azimuth were used to interpret both basement and sediment propagating normal faults that extended...

... by using a geostatistical approach, kriging with external drift method - software ISATIS, and by considering the correlation between the calibrated heat flow value at single well and the geological trend. Over the study area the heat flow trend correlates both with seismic and magnetic basement...

... Abstract Fracture data from borehole images has been a critical portion of well data for the fractured granite basement reservoir characterization for long in Vietnam. However, acquiring good quality electrical borehole images can be often challenging due to extremely high formation...

... incorporated with borehole image interpretation, provided important insights in understanding the productive reservoir facies. A conceptual geological model for the Ingoli basement reservoir is developed by integrating all the boreholederived geological information with seismic and reservoir analysis...

... Abstract The oil-bearing, fractured granite basement rocks are a very important and complicated hydrocarbon reservoir in offshore Vietnam. However, the poor S/N ratio and imaging of these steeply dipping fractures by conventional Kirchhoff migration are quite difficult to interpret...

... Abstract The fractured granite basement in the Nam Con Son basin of southern offshore Vietnam has become a new exploration target in recent years. However, there are two major challenges in the early days of exploration. First of all, it is not always easy to locate a drilling target...

... Introduction This presentation describes the geological characteristics, technical issues and development challenges associated with hydrocarbon exploitation in crystalline basement formations. The term 'basement' here refers to crystalline formations ranging from intrusive and extrusive...

... demand a state-of-the-art migration algorithms to honor the details that are needed in imaging the relevant complex structures. Controlled Beam Migration (CBM) is one of those techniques that exhibit an excellent impact on imaging Fractured and Faulted Granite basement. The velocity model that is used...

... is currently being undertaken by several companies. The hydrocarbon systems, both known and speculative in this area are influenced by the basementmorphology. The late Proterozoic amalgamation of the crystalline basement terranes has resulted in a heterogenous base to the sedimentary section. The reactivation...

... styles and detailed structural geometries into a unified tectonic model. This resulted in a better and more thorough definition of the structure and hydrocarbon distribution of Abu Dhabi in the context of the entire Arabian Platform. The observed structures resulted from gentle basement inversion, salt...

... hydrocarbon recovery, and to improve subsurface targeting of wells. The fault pattern of the rift basin is organised according to a number of highly interlocking but laterally persistent trends, most of which are inherited from already existing anisotropies in structural basement and its pre-rift overburden...
